I'm looking forward to my hair turning dark brown again (hopefully!).
To my understanding, my hair turned prematurely gray at 24 (now 28) because I became deficient in bio-available copper.
Once I detox the excess copper in my body (liver etc) it should go back into the bloodstream again and deposit itself back into my hair, recoloring the hair.
Well, that's the theory anyway. If I'm wrong, please correct me.
